Potential method to better control lung cancer using radiotherapy

Standard treatment for locally advanced non-small cell lung cancer is a combination of radiotherapy and chemotherapy. Traditionally this is planned in a one-size-fits-all manner but the radiation dose may not always be enough to stop tumor growth. The potential to increase the radiation dose to the cancerous tissue varies between patients and depends on the size and location of the tumor in relation to sensitive organs such as the spinal cord and lungs. …

New estrogen-based compound suppresses binge-like eating behavior in female mice

“Previous data has shown that women who have irregular menstrual cycles tend to be more likely to binge eat, suggesting that hormones in women play a significant role in the development or prevention of the behavior,” said Dr. Yong Xu, assistant professor of pediatrics and senior author of the paper. “Previous data has also shown that in humans, there is a strong association between estrogen and binge eating. …

New biomarker highly promising for predicting breast cancer outcomes

Cancer is deadly in large part due to its ability to metastasize, to travel from one organ or tissue type to another and malignantly sprout anew. The vast majority of cancer deaths are associated with metastasis. In breast cancer, a process called “epithelial to mesenchymal transition” aids metastasis…

Scientists map risk of premature menopause after cancer treatment

The findings, set out in the Journal of the National Cancer Institute, are based on the experience of more than 2,000 young women in England and Wales treated for the cancer over a period of more than 40 years. Previous research has suggested that women with Hodgkin lymphoma who receive certain types of chemotherapy or radiotherapy are at increased risk of going through the menopause early — but there was insufficient information to provide patients with detailed advice. But the new study, led by scientists at The Institute of Cancer Research, London, provides precise estimates of risk for women depending on which treatment types and doses they received and at what age — allowing doctors to give them detailed advice about their risks of future infertility…

Treatment for overactive bladder and irritable bowel syndrome advanced through pioneering research — ScienceDaily

The new study, published in The FASEB Journal, has found that this clock activity in turn regulates the cycle of all cells in the body. The team of researchers also discovered that the local biological clock and its control are weakened in aging bladders, demonstrating the importance of the clock in bladder physiology and aging. While currently much is known about the central biological clock, little is known about the peripheral clocks in the body. This latest research challenges the long-held view that the central clock of the brain controls all the peripheral clocks in other parts of the body and that these in turn control the down-stream receptor molecules which generate specific cell activities, such as contraction, secretion and metabolism…

High concordance between EGFR mutations from circulating-free tumor DNA and tumor tissue in non-small cell lung cancer

EGFR tyrosine kinase inhibitor (TKI) therapy is approved for EGFR activating mutation positive patients with advanced NSCLC, but the standard for determining mutation status is with DNA derived directly from tumor tissue, which can be limited or not available. …

Study identifies protein that helps prevent active tuberculosis in infected patients

The discovery could help doctors identify people who are at the greatest risk for the highly contagious and potentially fatal lung disease, and it could point the way toward new treatment strategies for TB. The study, conducted in partnership with researchers from Harvard University School of Public Health and the University of Michigan School of Medicine, was published in the Aug. 20 online edition of the journal Science Translational Medicine…

Novel gene predicts both breast cancer relapse, response to chemotherapy

Despite advancements in cancer treatment, breast cancer remains the most common cancer among Singapore women. Thirty percent of early breast cancer patients in the world experience relapse due to metastasis, or the spread of cancer cells to other organs in the body. Some patients also do not respond well to chemotherapy…
